Most of the running shoes They feel comfortable the first time you use them, but the real test is done after certain kilometers during a race.
The running shoes They have much more to do with their style of stepped and foot shape than with the logo on the letter.
In general, a couple of running shoes must last between 400 to 500 race miles, this implies between 3 or 4 months for regular runners.
However, other external factors come into play as its cushioning quality and compression between its midsole.
How to choose running shoes?
Among other factors to take during the selection are divided into:
Show a wear pattern centralized to the ball of the foot and a small portion of the heel. It is the natural inside turn of the foot after the heel that hits the ground. Basic pronation (neutral) helps absorb the impact, relieving pressure on the knees and joints. It is a normal feature of the corridor
It is identified by the wear patterns along the inside edge of your shoe, and is an exaggerated form of the natural inner roll of the foot. Over-pronation is a common feature that affects most runners, which puts them at risk of knee injuries and pain.
These runners need stability or neutral and biomechanically efficient movement control shoes.
It is marked by wear along the outer edge of your shoe. It is a swing out of the foot that results in an insufficient impact reduction in the landing. Relatively few supine runners, but those who do need shoes with a lot of cushioning and flexibility.
What is the function of cushioning in running shoes?
The damping is very related to the perceived comfort of some sneakers, among other topics is also the balance.
To achieve a really comfortable footprint shoe companies have developed a characteristic foam that not only improves the softness, but also prevents multiple lesionss.
Many companies from Under Armor to Asics use TPU (thermoplastic polyurethane) beads to offer a more sensitive firmness, this together with the new HOVR foam creates a feeling of zero gravity.
Characteristics of the cushioning
The midsole is the layer of cushioning and stability between the upper part and the sole.
The EVA (ethylene vinyl acetate)
It is a type of foam that is commonly used for the midsole of running shoes. Shoe cushions often use a single layer of EVA. Some will insert multiple EVA densities to force a particular bending pattern.
Areas of Eva
Stronger EVA areas (double density, quad density, multiple density, compression molding) are added to create more difficult sections to compress in the midsole.
Often found in stability shoes, the poles are used to slow down pronation or increase durability.
The medial sides reinforce the side of the arch of each midsole, an area highly impacted by over-pronation. The plates are made of a thin and somewhat flexible material (often nylon or TPU) that reinforces the forefoot of the shoe.
This contemplates the midsole and how it protects the heel along with the arch. They increase the firmness of a shoe when traveling on rocky terrain. Ultra-light backpackers often use light trail runners with protection plates and rods for protection and support.
TPU (thermoplastic polyurethane) is a flexible plastic that is used in some midsoles as a stabilization device.
Why choose cushioning in the shoes?
A padded sneaker is a preferred option for runners who are prone to injury and need additional support. However, if you are new to that feeling of running in the clouds, we advise you to take it easy with all new shoes.
Characteristics in running shoes
El Synthetic leather is a flexible material, durable and resistant to abrasion derived mainly from nylon and polyester.
It is lighter, faster drying and more breathable than real leather. In addition, it does not require (or very little) interruption time.
The nylon and nylon meshes They are the most used durable materials for reduce weight and increase breathability.
The TPU layers (thermoplastic polyurethane) are placed on the breathable panels of the shoe (as in the arch and heel). These small abrasion resistant additions help improve stability and durability.
The waterproof / breathable tops use a membrane attached to the inside of the linings. This membrane blocks the entry of moisture and allows the feet to breathe.
